PERT solar cell new solar technology that is 22 percent efficient than usual solar cell. Independent semiconductor nanotechnology research institute imec. That is a member of Energty Ville, a sustainable energy research association in the Belgian-Flanders region.
The firm has converted the front side of a double-side irradiated n-type PERT solar cell (Bi-PERT) for improved efficiency. on April 18 they have announced that they have succeeded in raising the efficiency up to 22.8%. Under standard front lighting conditions.
Improved Efficiency PERT solar cell
So about 15% of sunlight was also irradiated on the back side. And conversion efficiency increases up to 26.2% with single side irradiation type solar cells. Bi-PERT has fingers of thin (<20 μm) nickel-silver (Ni / Ag) plating on both the n + side and the p + side. And the solar cell contacts are patented to simultaneously plating both sides.
PERT solar cell Grid Touch System
And this technology is succeeded in raising the conversion efficiency on the front side to 22.4% in the average conversion efficiency and 22.8% in the maximum. These results were obtained using the Grid Touch system under standard test conditions. By using only front lighting and non reflective chucks that are based on the reference cell correctly calibrated by ISE CalLab .
According to Filip Duerinckx, a principal engineer at solar cell development at imec. “Generally, silver was applied to both sides of the solar cell by screen printing. But by replacing it with nickel-silver plating, silver we have reduced the amount of usage and reduced manufacturing costs. So at the module level, the manufacturing cost is less than 0.30 dollars / Wp.
And the leveled cost of electricity (LCOE) in the case of installing large solar power generation facilities is to decrease.
